What is Cryptocurrency? and How Does It Work ? Why Do We Use It ?

  • by

Virtual trading platforms created and used by private individuals or groups are cryptocurrencies or virtual currencies. As most cryptocurrencies are not controlled by national governments, alternative currencies are considered–financial exchange media that operate outside the limits of state monetary policy.

Bitcoin is the largest cryptocurrency and is first widely used. Nevertheless, there are hundreds of cryptocurrencies and there are more each month in the spring.

What does cryptocurrency mean?

To protect their exchange units, cryptocurrencies use cryptographic protocols or extremely complex software systems that encrypt sensitive data transfers.

Such protocols were developed by Cryptocurrency developers based on advanced mathematics and computer engineering principles that render them almost impossible to break, thus duplicating or counterfeiting protected currencies. These protocols often obscure the identities of cryptocurrency users, making it difficult to connect transactions and funds to individuals or groups. This Benzinga Money article discusses the fundamental principles of cryptography.

Decentralized control

Decentralized governance also characterizes cryptocurrencies. The supply and price of cryptocurrencies are regulated by their users ‘ actions and by highly complex protocols included in their codes of governance, not by the conscious decision of the central banks or other regulatory authorities. Mining operations–in particular, cryptocurrency users who use enormous amounts of computer power to record transactions, obtain newly developed cryptocurrency units and transaction costs charged in return by other users–are essential for the stability and smooth operation of currencies.

Exchange with currencies of Fiat

Importantly, in special on-line markets, fiat currencies may be traded with each of the major world currencies (such as the US dollar, British pound, European euro, and Japanese yen). Crypto-currency exchanges are vulnerable to hacking and are the most commonplace for hackers and cybercriminals to digital currency theft.

Finite supply

Many, but not all, cryptocurrencies have finite supply characteristics. Their origin codes provide information on how many units can and will ever exist. Over time, miners find it harder to produce crypto-currency units until the upper limit is reached and the new currency is no longer being minted. The finite supply of cryptocurrencies renders them deflationary necessarily, more like gold and other precious metals–of which there are restricted quantities–than fiat currencies that central banks can produce unlimited supplies of, in principle.

Benefits and consequences

Because of its political independence and virtually impenetrable data security, consumers of cryptocurrency have a non-U.S. dollar and financial systems that are funded by these currencies. For example, while a Government can easily freeze or even seize a bank account located in its jurisdiction, it is very difficult for a state, even if the owner is a citizen or a legal resident, to do the same with funds held in cryptocurrency.

Cryptocurrencies, on the other hand, come with many risks and drawbacks, including illiquidity and price fluctuations, which do not affect other fiat currencies. Furthermore, cryptocurrencies are often used to facilitate gray and black market transactions, so many countries treat them with suspicion or antagonism. And while some advocates regard cryptocurrencies as potentially lucrative alternatives, few (if any) serious financial professionals regard them as appropriate for anything but pure speculation.


How many are there, and what are they valuable?

According to CoinMarketCap.com, a market research website, more than 2,200 separate cryptocurrencies are publicly traded. And cryptocurrencies continue to grow, raising money through initial offerings of coins or ICOs. According to CoinMarketCap, the total value of all cryptocurrencies on 6 June 2019 was around 246 billion dollars, and the total value of every Bitcoin, the most common digital currency, was around 136 billion dollars.

Why is it so popular?

Cryptocurrencies cater for several reasons to their backers. Some of the most popular ones: supporters see cryptocurrencies like bitcoin as the future currency and are looking to buy it now, probably before they become more expensive. Many supporters like the fact that cryptocurrency prevents central banks from controlling the money supply, since these banks tend, over time, to reduce the value of money through inflation.

Cryptocurrencies can increase value, but many investors see it not as actual investments, but as pure speculations. The explanation for this? Unlike traditional currencies, cryptocurrencies do not produce cash flow, so that someone pays for the currency more than you do to benefit.

That’s what is called the “big stupid” investment theory. In comparison, it increases its value over time by increasing the revenue and cash flow of the company.

For those who consider cryptocurrencies like bitcoin as the future money, it is worth noting that a currency needs stability.

As writers of NerdWallet reported, cryptocurrencies like bitcoin might not be free, and some impressive voices in the investment field have advised potential investors to get rid of them. In particular, the legendary investor Warren Buffett compared bitcoin to paper checks: “This is a very effective way to transfer money and you can do this anonymously and anonymously. A check is also a way of sending cash. Are controls worth a lot of money? Only because they can send money?”For those who see cryptocurrencies such as bitcoin as the future currency, the currency must be stable to determine what a fair price is for goods. Bitcoin and other cryptocurrencies throughout much of their existence have been anything but stable. For example, while in December 2017 Bitcoin traded at almost $20,000, its price then plummeted to about $3,200 a year ago. It topped $8,000 in May 2019.

This instability in rates causes a mystery. While bitcoins will be much worth more in the future, people are less likely to invest and exchange them now, making them as currency less viable. Why invest a bitcoin when next year it could be three times the value?

How can I buy cryptocurrency?

While some cryptocurrencies such as bitcoin can be bought in U.S. dollars, others require you to pay in bitcoin or another cryptocurrency.

You’ll need a’ wallet’ to buy cryptocurrencies, an online application that can hold your currency. In general, you create an exchange account and then transfer real money to purchase cryptocurrencies like bitcoin or ethereum. Here’s more on trading in bitcoin.

Coinbase is a popular cryptocurrency trade where you can both create a wallet and purchase and sell bitcoin and other cryptocurrencies. Also, Robinhood online broker provides free cryptocurrency trades (Robinhood Crypto is available in most, but not all, United States states).


How does cryptocurrency work?

Cryptocurrency is equivalent to other kinds of digitally stored payment methods, such as PayPal or debit cards. The cryptocurrency system uses a blockchain to generate digital currency and monitor transactions at a controlled rate.

Digital money can then be moved to another account from one account or a digital wallet to buy goods or services from companies such as yours.

Crypto-monetary is decentralized, which means that the money (pound sterling, US dollars, etc.) isn’t controlled and supervised by one central authority, such as a bank or state. Alternatively, the process and users manage and control the ledger collectively.

While everyone can display and access the ledger, individual identities are encoded with pseudo-anonymous or special sets of keys. Such unique sets of keys bind the individual to an account and the account’s cryptocurrency.

Main terminology of cryptocurrencies.

Perhaps the single language is one of the greatest challenges in understanding cryptocurrency. Newbies may consider words like blockchain, proof-of-work, cryptocurrency mining and digital wallets confusing. Blockchain A distributed public repository of records (known as blocks), which are secured and connected through cryptography or encryption. Blockchains are extremely secure as they can not be modified until data is entered into them.

This level of security is well suited to a variety of applications such as intelligent contracts and cryptocurrencies. In the latter, blockchains are operated by peer-to-peer networks and used to record financial transactions securely.


To confirm the authenticity of transactions, cryptocurrency programs use timelines. Most cryptocurrencies, such as Bitcoin, have a proof of work scheme using SHA-256 and scripting the timestamp (or password-based keys).

Mining of cryptocurrency

Transactions are verified by cryptocurrency mining and added to the blockchain. To obtain the required hash function, miners have to solve complex mathematical codes. These Hash functions are essential to confirm transactions and to add them within the blockchain to the previous block.

As the good miner earns cryptocurrency, mining is very competitive and some people make a living. Nevertheless, miners must invest in advanced computers because their average machine is too sluggish to compete effectively.

The success of cryptocurrencies, in particular, Bitcoin, has made the mining industry very competitive and almost impossible to gain.
